Perfect for our server room

We installed three of these units in our data center. The RS485 integration with our existing BMS was seamless, and the LCD display makes local checks very easy.

Accurate and sturdy

The build quality is excellent, fitting perfectly into standard 86mm boxes. Readings match our calibrated handheld meter within the specified tolerance. Setup took about 20 minutes.

Great value for industrial monitoring

Needed a reliable solution for our document archive to prevent mold. This sensor provides consistent data logging capabilities when connected to our gateway. Highly recommended.

Good display visibility

The LCD screen is bright and easy to read from a distance. The only minor issue was that the wiring diagram could be clearer, but support helped us sort it out quickly.

Reliable Modbus performance

No communication drops since installation two months ago. The humidity readings are stable and react reasonably fast to changes in the room environment.

Exactly what we needed

Compact design that doesn't look out of place on the wall. The temperature and humidity accuracy is sufficient for our pharmaceutical storage compliance needs.

5 FAQ

Q: Is the LCD display backlit for low-light environments?

A: The standard model features a clear LCD without an active backlight to reduce power consumption, but the digits are large and legible in typical indoor lighting.

Q: Does this sensor come with the mounting screws for the 86 shell?

A: Yes, the package includes the necessary screws to mount the unit onto a standard 86mm junction box.

Q: Does this device log data internally if the connection is lost?

A: This specific model acts as a real-time transmitter and does not have internal storage; it requires a connected host system or gateway to record historical data.

Q: Can I connect multiple sensors to a single RS485 converter?

A: Absolutely. You can daisy-chain up to 247 devices on a single RS485 bus, provided each has a unique Modbus address configured.

Q: What is the cable length recommended for RS485 connection?

A: For reliable communication at 9600 baud rate, you can extend the cable up to 1200 meters using twisted pair shielded cable.
